Martens scored in the closing stages to give Louis van Gaal's men their first victory of the campaign and knock PSV off the top of the Eredivisie.

The former RKC Waalwijk striker chipped goalkeeper Andreas Isaksson in the 83rd minute as Huub Steven's charges suffered their second defeat in a week following the midweek Champions League loss to Atletico Madrid.

A late goal from substitute Petter Andersson ensured FC Groningen moved to the top of the table with a 1-1 draw at Heracles Almelo.

The draw represented an excellent result for Ron Jans' men, who played almost the entire game with 10 men following the second-minute dismissal of Oluwafemi Alijore.

Bas Dost put the hosts ahead five minutes into the second half when he headed home Darl Douglas' cross, but Groningen battled on bravely and got their reward with six minutes remaining as Andersson converted a cross from fellow substitute Berry Powel.

Vitesse Arnhem and Sparta Rotterdam both got off the points mark with a 1-1 draw, although a first win of the season remains elusive for the two clubs.

Following back-to-back defeats, Ricky van Wolfswinkel finally gave Vitesse fans something to cheer about shortly after the interval with their first goal of the campaign.

But Sparta were determined to avoid a third successive league loss themselves and Charles Dissels netted a deserved equaliser for the Rotterdam side.
